Concept explainers
Part (a)
Force experienced by electric charge at rest when placed in a magnetic field of a magnet.
Solution: Electric charge at rest will not experience any force.
Part (a)

Explanation of Solution
Static Electric charge will not experience any force because according to the Lorentz relation
Conclusion: An external magnetic field always exerts force of other magnets and charge particles.
Part (b)
To determine: - Force experienced by moving electric charge when placed in magnetic field of a magnet.
Part (b)

Answer to Problem 1OQ
Solution: - Moving electric charge may or may not experience a force.
Explanation of Solution
Explanation: - Dynamic Electric charge will not experience a force if its direction is parallel or anti-parallel to the direction of magnetic field. And with respect to any other direction it will experience a force.
According to Lorentz relation,
For parallel (
So,
Conclusion: - An external magnetic field always a force on other magnets and charge particles.
Part (c)
To Determine: - Force experienced by
Part (c)

Answer to Problem 1OQ
Solution: - Electric current in a wire will experience a force.
Explanation of Solution
Explanation: - Electric current in a wire will experience a force because current is only due to moving charges and magnetic field always exerts a force on moving charges so, conductor will also experience a force.
Conclusion: - Every conductor experiences a force given by a relation
Part (d)
To Determine: - Force experienced by another magnet when placed in magnetic field of a magnet.
Part (d)

Answer to Problem 1OQ
Solution: - Another magnet will experience a force.
Explanation of Solution
Explanation: - Another magnet always experiences a force because it is a natural property of a magnet, but this force can be repulsive or attractive depending on the nature of poles of a magnet.
Conclusion: - Magnetic force between the magnets is inversely proportional to the distance between them.

A motorboat traveling 6 m/s, West encounters a water current travelling 3.5 m/s, South. a) Draw a vector diagram showing the resultant velocity, then determine the resultant velocity of the motorboat. b) If the width of the river is 112 m wide, then how much time does it take for the boat to travel shore to shore? c) What distance downstream does the boat reach the opposite shore?arrow_forwardLake Erie contains roughly 4.00⋅10114.00⋅1011 m3 of water. Assume the density of this water is 1000. kg/m3 and the specific heat of water is 4186 J/kg˚C. It takes 2.31x10^19 J of energy to raise the temperature of that volume of water from 12.0 °C to 25.8 ˚C. An electric power plant can produce about 1110 MW. How many years would it take to supply this amount of energy by using the 1110 MW from an electric power plant?arrow_forward
